Application filed November 18, 1914. SeriaI No. 872,826.

To 07.7 11-710; it m (0 concern:

lie it known that I, \VILLIAM BLANEY, of ltfarblehead, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Heels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v

The primary object of this invention is'to provide means for attaching yielding heel lifts without the use of nails or screws, thereby avoiding all liability of scratching smooth or polished floors, decks, etc., and avoid not only the wear of the exposed surfaces of the fastening means, but also the accumulation of dirt or snow in the sockets in which such fastening means has heretofore been countersunk.

A further object is to provide improved means for securing yielding heel lifts in place by means which while permitting such lifts to be changed from one heel to the other to insure uniformity in wear, will effectively prevent any accidental displacement of the yielding lift.

In the accompanying drawing, Figure 1 is a view in perspective. Fig. 2 is a view showing the fixed and removable lifts separated. Fig. 3 is a central longitudinal sectional view.

Referring to the drawings, I designates a fixed lift or heel section formed with two transverse ribs 2 of dovetail formation in cross section. This fixed lift may be made of wood, leather, or any suitable fiber.

3 is the removable lift or heel section which is formed with two transverse grooves 4 designed to receive the transverse ribs 2 of the fixed lift so that the removable lift may be attached and detached by a relative transverse sliding movement between the two lifts. The removable lift is formed of rubber or other suitable resilient material. After'the two lifts have been secured together by a relative lateral movement, they.

secured in place by anysuitable means, but

I prefer to form it with an external thread for fitting 1n threaded bushings in. the walls Patented June 1915.

of the removable lift, the end of said keyrod being grooved to enable it to be readily turned by an ordinary screw-driver. The end of this key-rod is flush with the forward end of the heel so as to guard against dirt getting in between the lifts. To further provide against anv accidental displacement of the removable lift and to hold it firmly along its edges against the ingress of dirt or" water, I employ cooperating studs and sockets. As shown in Fig. 2 the lower face'of the fixed lift may have a series of short studs 6 projecting at right-angles therefrom and designedto fit in sockets 7 of the removable lift, the engagement and disengagement of the studs and sockets being effected by a slight bending outward of the removable lift as it is being adjusted to or removed from the heel. These studs and sockets so 'hold the removable lift that there is no danger of its being accidentally knocked off or separating from the fixed lift so that foriiiign substances might enter between the two i ts.

I have shown the removable lift as having sections of nonslipping material cored therein. For this purpose I preferably emplov pieces of cork 8. the lower surfaces of which are designed to be flush with the surface of the removable lift.

The advantages of my invention will be readily appreciated by those skilled in the art. It will be seen that there. are no sockets in the lower face of the removable lift and no exposed fastening means. and also that by reason of the transversely arranged interenga ging portions the outer heel section is firmly secured, but that in addition thereto the parts are locked against all possibility of displacement by the centrally disposed key passing through the overlapping portions of the lifts. The use of the interlocking studs and sockets is not absolutely essential, butin some circumstances it is advisable. By means of my invention ,the outer lift may be readily removed so as to be transferred from one heel to the other of a pair of shoes so as to insure evenness of wear. y

I claim as my invention: 1. A shoe-heel having a fixed lift and a removable lift, said v lifts having interengaging slidably connected portions extending transversely of the heel, studs projecting at right angles from one of the lifts, the other lift having sockets to accommodate said studs, said studs and sockets being constructed and arranged to prevent separation of the lifts in a direction normal to their faces, and securing means extending from the breast of the heel and longitudinally of the latter and transversely through said interengaging portions for locking them together.

In testimony whereof, I have signed this specification in the-presence of two subscribing witnesses.
